Here is a nebula visible with the naked eye if you live in the Northern Hemisphere. In the constellation Orion just below Orion's belt is a line of 3 evenly spaced bright stars known as Orion's sword. The middle star is not a single star but the bright nebula shown above. Orion's Nebula is one of the closest star forming regions to Earth and is only 1,400 light years away. This photo was taken by the Wide Field Imager camera on the MPG/ESO 2.2-metre telescope at the La Silla Observatory, Chile.
